So, i try to learn how to Drag and Drop an Image from one PictureBox to another and that works well. But how can i drag and drop the Image TAG from pictureox1 to picturebox2?
i currently have 3 source images and 3 drop boxes. the dropbox6 is locked with a countdown after a buttonclick (see button2)
(later i will lock all dropboxes)
after i hit this button a countdown starts and if the countdown is 0 (ZERO) only then i can drag one of the 3 images to this box.
however, i have given each of these 3 images in the souceboxes a TAG name. how can i drop this tagname also to the dropbox?
here is what i have so far: (the Label labeled "Counter" is actually Label4 in the code

i'm stuck. i tried this:
private void pictureBox_MouseDown(object sender, MouseEventArgs e)
{
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Image, DragDropEffects.Copy);
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Tag, DragDropEffects.Copy);
}
private void Form1_Load(object sender, EventArgs e)
{
pictureBox4.AllowDrop = true;
pictureBox5.AllowDrop = true;
pictureBox6.AllowDrop = true;
pictureBox6.Enabled = false;
pictureBox1.Tag = "Wood";
pictureBox2.Tag = "Stone";
pictureBox2.Tag = "Food";
}
and then in the drop this and getting a NULL Error
private void pictureBox6_DragDrop(object sender, DragEventArgs e)
{
Image getPicture = (Bitmap)e.Data.GetData(DataFormats.Bitmap);
pictureBox6.Image = getPicture;
var data = e.Data.GetData(pictureBox6.Tag.ToString());
pictureBox6.Tag = data;
label4.Text = data.ToString();
timer1.Enabled = false;
}
im starting to get anoyed.....haha im probably close and its just a tiny misstake. i have no idea...in my opinion it should work.
need help. thank you i might be able to zip the whole thing and provide a download link? is this allowed here?
CodePudding user response：
In MouseDown you are saying what you want to transmit in the DoDragDrop call. In your current case you are transmitting the image ((PictureBox)sender).Image but you can chose to transmit the tag as well...
private void pictureBox_MouseDown(object sender, MouseEventArgs e)
{
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Image, DragDropEffects.Copy);
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Tag, DragDropEffects.Copy);
}
...Then make sure to parse for each possible input type in DragDrop
private void pictureBox6_DragDrop(object sender, DragEventArgs e)
{
var image = e.Data.GetData(DataFormats.Bitmap) as Bitmap;
var tag = e.Data.GetData(DataFormats.Text) as string;
if (image != null)
{
pictureBox4.Image = image;
}
if (tag != null)
{
pictureBox4.Tag = tag;
}
timer1.Enabled = false;
}
Beware, that you will need to update all the code that checks that the data is Bitmap before it arrives at DragDrop ie in DragEnter and write code that handles both Bitmap and Text, otherwise the Drag functionality will break.
